Top-Rated HVAC Services in Waco, TX 76705 - A & H Refrigeration

It sounds counterintuitive, but evaporator coil freeze-ups are a common issue during our hot Waco summers. This is often caused by restricted airflow from a dirty air filter or blocked vents, or by low refrigerant levels. Both prevent the coil from absorbing heat properly, causing it to get too cold and freeze. Our technicians can quickly diagnose the root cause—whether it's a simple filter change or a refrigerant leak repair—to get your system cooling efficiently again.

Absolutely. Sudden AC failure during extreme heat is a frequent emergency call we handle in Waco. It's often due to the system being overworked, which can trip a safety breaker, cause a capacitor to fail, or lead to a compressor issue. We offer prompt emergency service to diagnose the problem safely and get your cooling restored as quickly as possible, because no one should have to endure a Texas summer without AC.

The single most effective thing you can do is change your air filter regularly, especially during peak cooling season. A clean filter ensures proper airflow, which is critical for preventing evaporator coil freeze-ups and helping your system run efficiently without overstraining in our heat. We also recommend a professional preseason tune-up to check refrigerant levels, clean the coils, and inspect electrical components, which can catch small issues before they lead to a breakdown on the hottest day of the year.
